2.
In this paper,it is applied to predict the height of water conducted zone under sub level caving method.
本文尝试将其应用于综采放顶煤条件下导水裂隙带高度的预测，结合新集矿１３０３综放工作面进行了模拟分析，根据采后覆岩应力变化特点及破坏状况确定出导水裂隙带高度。
3.
The regression equation and expectancy map of the water conducted zone in mine area were made.
在借鉴国内外覆岩破坏研究经验和分析新安煤矿水文地质条件基础上,采用FLAC 3D数值模拟、钻孔漏失量监测和井下仰孔并行网络电法CT探测技术对小浪底水库下开采覆岩破坏规律进行了分析,并获得了回归关系式和全煤厚开采导水裂隙带分布预测图,为大型水库下防治水决策提供了科学依据。
